Application inea November ze, 1900. serial No. 37.969 (11515011515 To all whom it may concern.'

Be it known that I, LUTHER F. H AYNES, a citizen ofthe United States, and a resident of Lunenburg, in the county of Worcesterl and State of Massachusetts, haveinventled an Improvement in Flushing-Tanks for Closets, of.-

Which the following description,in connection with the accompanying drawings,k is a speciication, like letters on the drawings repre- 1o senting like parts.

This invention relates more particularly to ushing apparatus for Water-closet.` ybowls and it has for its object Vthe production of novel means for accomplishing thev desired I5 results in a simple and very eflicient manner.

My invention belongs to Vthat typeof such apparatus whereinthe liushing system is in4 direct communication with the city water mains or pipes, the tankwhich forms a part zo of my novel apparatus containingno valves,

floats, or othermovable devices, a single con.

trolling-valve external'to thevtank serving to govern the iiushing operation.

Variousjnovel 'features of my invention will be hereinafter described in the specifica-V tion, Aand particularly pointed out in the following claims.

Figure 1 is a view,principally in vertical section, of a flushingapparatus' embodying 3o one practical form of 'my invention; and Fig.

2 is a side elevation of the valve-actuatingV drum to the right of the line a: fr, Fig. 1.

' Referring to Fig. 1, I have shown a closed air-tight tank comprising ends or heads a, b and a side Wall c, preferably made of metal,

the heads being rigidly secured to the side v wall in any suitable manner-as, for instance,

, by threaded connections ax bx. The head a is shown as provided with an external tubu- V 4o lar boss a',externally threaded at of* for conlatter forms the inlet of :the throat,ylle supply-pipe being concentric with the throat. A valve-case dx'is securedto thethreaded end b4 of the discharge or outlet pipe bjg'an'd the outlet forthe valve-casecommunicates with a pipe F, which leads tothe closet-bowl,of any usual construction. (Not shown.) -A'valve d, mounted to'slide back and forth relatively to the seatd, isv threaded'ato'receive,acorre# spondingly threaded rotatable` spindle (12,60

mounted in the 'valve-case, the'` valveylbeing shown open in Fig. 1.l Rotation of the spindle injone direction or thel other' opens or closesthe valve, the valve; mechanism'per se 5 not being of my invention, and any other suit- 65 l Sable valve mechanism may be used instead of" that herein illustrated Without departing .fromithe spirit and scopelof my invention. A 5

'double drum or sheave G Gis shown as vfast on the valve-spindle', the larger dr`u'm G hav- 7c.

ingywoundfupon'it'and,1attached thereto an actuating-'chain g, provided' Vwith a suitable handle'gx, Fig. 2, Whilethe smaller d rum G' ,has oppositely Wound upon it, and, secured at 'one end achain 92,130 the free end of which 75 c 'a'fvveight g3 is secured, heavy enough to normally turn the spindle inthe' .direction of are*A rowA 10 to shut the valve. r

vSuppo'sing the connections with servicei main and closet-bowl to be properly made, opening of the valve d permits the water to rush through the supplypipe as with city pressure into the contracted throatr b2 and through the valve-case tothe iiushing-pipe F and bowl, flushing the latter; but the stream of water rushing through the throat exhausts the air in the tank, so that a vacuum is produced therein, the action being similar to that of the injector. When the valve is thereafter shut, the Water continues. t0 lowfrom 9o the supp1ypipe c3; but it passes back through the throat into and lls thetank, -the"1flow stopping when the latter is i l led.` When next the valve isopened, the waterfrom" the supply-pipe again rushes through the throat; but this time it draws with it the body of water stored'in the tank, so that the flushing of the closet-bowl is effected not only by the incoming Water under service-pressure, but also by the' volume of stored water in the tank. The Iool fact that the service-pressure is utilized in connection with the stored body of water enables a tank of comparatively small capacity to be employed, with the attainment of a much more eective and complete iiushing than is possible with otherflnshing apparatus known to me, and the advantageous features of my invention over the well-known open -tank structure will be manifest. The emptying of the tank when flushing obviously forms a vacuum therein, so that after the controllingvalve is shut the tank will refill automatically.

I have shown the tank-outlet b3 as of large area compared to the area of the supply-pipe a3, so that the tank will rapidly discharge its contents.

The principle of operation of the apparatus obviates the location of the tank, so that head is provided, and the elimination of all movable partssuch as valves,floats, dto.- in the tank makes the apparatus durable and quick in operation, and there is no liability of its getting out of order. The closed tank prevents overow or leakage.

I have shown one practical embodiment of my invention without attempting to illustrate Various changes or modifications which may be made by those skilled in the art without departing from the spirit and scope ofthe invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A closed tank, an outlet-pipe leading therefrom, a valve in said pipe to control the discharge from the tank, the said outlet-pipe between the tank and valve being provided with a throat of gradually-decreasing crosssectional area from the tank to the valve, and a supply-pipe leading into the outlet-pipe and extended into the contracted portion thereof v between the tank and valve.

2. A closed tank, a straight outlet-pipe connected to the bottom portion of said tank, a valve in said pipe for controlling the discharge from the tank, the opening in the said outletpipe gradually contracting from the tank to the valve, and a supply-pipe concentric with said outlet-pipe and extended into the contracted portion thereof above the valve.

3. A closed tank, a discharge-pipe leading from its bottom, a controlling-valve in said pipe, the said pipe contracting gradually between the tank and valve, a relatively small supply-pipe concentric with the dischargepipe and extended into the latter, the end of the supply-pipe being located in the contracted portion of the discharge-pipe between the valve and tank.

4. A closed tank, a discharge-pipe communicating with its bottom, a supply-pipe entering the top of the tank and extended downward into and concentric with the dischargepipe, a controlling-valve in the latter, beyond the mouth of the supply-pipe, a manual actuator for the valve, and means to automatically close the valve.

5. A closed tank having a large outlet in its lower end, a discharge-pipe leading therefrom and having a contracted throat, the outlet forming the entrance thereof, a relatively small supply-pipe entering the tank through its upper end and extended downward through the outlet and into the throat concentric therewith, and a controlling-Valve in the dischargepipe beyond the mouth of the throat, a rotatable spindle on which said Valve is threaded to slide, and means for turning said spindle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
